Since Divergent hit screens last year, fans of the book-turned-movie have been anxiously awaiting its sequel, Insurgent. Filming is under way in Georgia with stars Shailene Woodley (Tris), Theo James (Four), and Ansel Elgort (Caleb), and lucky for us, they've been sharing pictures from the set. Even cast newbies like Suki Waterhouse (Marlene), Emjay Anthony (Hector), and Octavia Spencer (Johanna) got in on the action with some fun snaps! Check out some behind-the-scenes social photos below, and then see everyone who is officially on board for the sequel.
